D.Va has this weird glitch, that is only really noticeable in custom game modes, but if it can be used in regular modes could be game breaking, basically it happens when you ult twice as dva, not sure if its bomb > remech or remech > bomb but it places you into a state where you are spectating where you died, and theres no way to fix this from when it happens. If this is used on an objective however, this may be some advanced form of cheating, or a huge inconvenience as the only fix is leaving. I will log on now and get a clip to show you

In addition the bug acted differently this time. Something to investigate
